Create variables with a loop? Jan25 '06
Let’s say I want to quickly create five new variables. It doesn’t matter what programming language we use.
Let’s use JavaScript, just for this example.
Instead of doing this:
var new_variable_1; var new_variable_2; var new_variable_3; var new_variable_4; var new_variable_5;
... I’d like to "group" this better, by doing something like this:
for (i=1; i<6; i++)
{
var new_variable_ + i;
}
See what I’m trying to do? By using the temporary variable i, I should be able to append that variable to the end of each variable I am creating. Make sense?
The problem is I’m not sure if I can add a variable value to a variable name.
Ahhh, only after you spend hours doing this crap, do you come up with such strange concoctions.
It’s not even 5 PM, and already I need a beer.
